the safety features. Features and details of 1n the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as fol lows: l

Fig. 1 shows an end elevation, partly in section, on the line I-I in Fig. 2.

Fig. 2 a front elevation of the wringer, partly in section.

Fig. 3 an end view ofla modification, said View giieing4 partly in sectionr on the line 3-3 in Fig. 4 a front View of the same modication, partly in section.

Fig. 5 a section on the line 5--5 in Fig. 2.

Fig. 6 a bottom view of one end of the top bar removed.

The frame has the baseI with the side stiles 2, the base being of channel form and the side stiles hollow shape. Rolls 3 and 4 have shafts 5 and 6 and these shafts are journaled in bearing blocks 1 and 8 mounted in the side stiles. A pressure spring 9 operates on the top bearing blocks. It is adjusted by a screw I0 operating in a nut II. The nut II is mounted in a top bar I2. v'I'he top bar is oi? channel form with the ends closed and is adapted to cover the upper edges of the stiles.

Notches I3 are arranged in the side stiles. Hooks I4 extending from the sides I5 of latches I6 engage the shoulders I3. The latches are pivoted on pins I1 extending between the walls i of the top. The latches are U-shaped in cross section, the top plate I8 of the latch having an extension I8a which engages an extension I9 on the trip plate 20.- The trip plate 20 has pivotal lugs 2l at its ends and these extend through openings 22 in brackets 23, the brackets being secured on the under-side of the top bar. In assembling the trip plate one bracket is secured, the pivot lug of the plate moved into this bracket and then the opposite. bracket is secured to the top plate. This bracket has a iiange 24, the bottom of which forms a stop 25 for the extension Idd, and so limits the movement of the latches I6. The latches are provided with projections 2B which are adapted to engage the tops of the stiles and assure the movement of the hooks into the notches, or under the shoulders I3. Springs 20a are provided at each side of the trip plate which yieldingly hold the trip 5 plate in its set position. The trip plate 20 has upwardly extending projections 21 which extend through openings 28 in the top plate. They have reduced extensions 23 which form shoulders 30 and an operating member in the form of a 10 plate 3l is seated on these shoulders, the'operat- 4ing plate having perforations receiving the extensions 29. The upper ends of the extensions 29 are headed over, or provided with nuts 32 by which the top plate is rigidly secured on the ex- 15 tensions'21. The operating member, or plate 3I has projecting portions 3 I a' extending to the front and back of the extensions 21 and connecting portions, or rails 3Ib connecting the portions 3Ia. These rails form the parts immediately engaged 20 by the operatorto trip the release.

In the operation of the device when the op-` erating plate 3| is tilted on either side of the wringer this swings the trip plate 20 with it carrying the trip extensions I9 oir the extensions I8a 5 thus releasing the latches. The top then yields and moves upwardly in response to the pressure of the spring and this movement relieves the rolls of the pressure of thespring. The latch mechanism by reason of the fact that the hook is practically below the pin I1 puts almost no pressure on the trip extensions I8a. and I9 so that the release is very sensitive. On the other hand, the engaging surface of the hook I4 is so shaped that when the latch .is released by the 35 trip plate there is an immediate movement of the latch to release the hooks.

In the structure shown in Figs. 3 and 4 the releasing mechanism as a whole is identical with that of Figs. l and 2 except that the operating 40 member 34 extends over the top bar forming a skirt for the top bar, this skirt preferably extending around the ends of the top bar and these ends stiiening the skirt and at the sametime adding to the finished appearance of the 45 wringer.

What I claim as new iszl. In a wringer, the combination ofa frame having a top bar; rolls mounted in the frame; pressure means between the top bar and the 50 rolls for exerting pressure from the top bar to the rolls; and a safety release device for the means comprising a member pivotally mounted on the top bar with its axis at the top of the top bar and extending longitudinally thereof, said bar 55 ing the trip member and the operating member,

said operating member extending to each side of the top bar and forming a skirt therefor, said skirt extending around the ends of the top bar.

3. In a wringer, the combination of a frame comprising a base and stiles; a top bar on the Stiles, said top bar being of channel form; a pressure means exerting pressure from the top bar on the rolls; a release device for releasing the pressure of the means having an operating member pivotally mounted on a longitudinal axis within the top bar and pivotally movable crossways of the top bar to effect a release; and an operating bar extending longitudinally of the wringer above the top bar and rigidly connected through the top bar with the operating member.
